BlackScreen after importing VM in Proxmox

[noname01]

Hello, I recently imported some VMs into my proxmox cluster, everything works fine except when I start the VM, the VM starts fine but I don't have a GUI and I have no idea (maybe drivers or something..) do you have any idea?

Thanks by advance

Hi,

Could you please post the VM config `qm config <VMID>`?

Hi,

The problem is on all the vm i imported, but this is the config of one i imported (to know, they was on Oracle Before the importing):

qm config 101

the VM starts fine but I don't have a GUI

1. How do you know it starts fine: Is it accessible via console or SSH?
2. Where/what GUI are you expecting from this VM?

I do Ctrl + Alt + F(x) and i can have an acces to the shell via tty(x)

I currently try to install a graphical environment, gonna update the thread

I'm now a little lost. Are you referring to the console of the VM (through PVE GUI) or something else. Maybe attached Monitor to Host?

In the VM?

 

[noname01]

Im referring to the VM console, here, after the import, i only have a shell and not a graphical environment like in my native VM.

Yes in the VM

UPDATE : The KDE Plasma graphical environment is not working

Stop VM, then in Proxmox GUI, go to VM, Hardware, change Display from Default to something else.

If this doesn't help, lets see if you can connect to the VM with a remote viewer.

I tried, but it change nothing...

(also, thank you for you help)

I guess you also tried a SPICE setup - correctly.
You don't mention on what system & how this VM previously (before import) worked. But it would appear to be an issue/driver within the VM itself (don't know which Linux OS). Start there. Not a Proxmox problem.

Yes, it's a Debian 11 (Bullseye), which was on Hyper-V before the import

Ok, thanks for the lead !
